The difference between remembering the past and not knowing the future primarily stems from the nature of time and how we experience it. Our ability to remember events is tied to our perception of the linear progression of time, which flows from past to present to future.
The past refers to events and experiences that have already occurred, and we remember them because they have been recorded in our memory. Our brains have the capacity to store and recall information about past events, which allows us to reflect on our personal history and learn from past experiences.
On the other hand, the future represents events and experiences that have not yet happened. It is inherently uncertain and unknown. While we can make predictions and plans for the future based on our knowledge and expectations, we cannot remember something that hasn't occurred yet. Our ability to recall events is limited to those that have already taken place.
Additionally, our understanding of the future is influenced by the concept of causality and the notion that events unfold in a cause-and-effect manner. We perceive the flow of time as moving from the past to the future, and our memories of the past serve as a basis for constructing expectations about the future. However, since the future is not fixed and can be influenced by various factors, it remains unknown until it becomes the present and eventually the past.
In summary, we remember the past because it has already happened and is stored in our memory, while the future is unknown and yet to unfold. Our ability to recall events is limited to what has already transpired, and our understanding of the future is shaped by our knowledge of the past and our ability to make predictions based on it.
